Being fully vaccinated against Covid-19 not only cuts the risk of catching it, but also of an infection turning into long Covid, research led by King’s College London suggests.
It shows that in the minority of people who get Covid despite two jabs, the odds of developing symptoms lasting longer than four weeks are cut by 50%.
This is compared with people who are not vaccinated.
So far, 78.9% of over-16s in the UK have had two doses of a Covid vaccine.
Many people who get Covid recover within four weeks but some have symptoms that continue or develop for weeks and months after the initial infection – sometimes known as long Covid. It can happen after people experience even mild coronavirus symptoms.
The researchers, whose work was published in The Lancet Infectious Diseases, say it is clear that vaccinations are saving lives and preventing serious illness, but the impact of vaccines on developing long-lasting illness has been less certain.
They analysed data gathered from the UK Zoe Covid Study app, which tracks people’s self-reported symptoms and vaccines and tests.
That meant that between December 2020 and July, the health was tracked of more than 1.2 million adults who received one coronavirus jab and 971,504 who received two jabs in that time frame.
- Just 0.2% of double-jabbed people said they had had a Covid infection after vaccination (2,370 cases)
- Of the 592 fully vaccinated people with Covid who continued to provide data for more than a month, 31 (5%) went on to get long Covid (defined as illness lasting 28 days or more after a positive test)
- In the unvaccinated group this figure was about 11%
Researchers found some people were more at risk of so-called breakthrough infections (getting Covid after a vaccine) than others – including frail, older adults and people living in deprived areas. This was particularly the case for people who had only had one jab.
